19、n) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be rep
20、resented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to dev
21、elop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the IS
22、O/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during

33、ing and reinforcement, between cover and reinforcement, between reinforcement layers, between cover and outer lamination and between lining and inner lamination is measured under specified conditions.5 Apparatus5.1 GeneralA test machine having the following characteristics is required:5.2 Test machi
34、neThe machine shall be power driven, equipped with a suitable dynamometer, capable of maintaining a substantially constant rate of traverse of the moving head during the test and fitted with an autographic recorder. It shall comply with the requirements for class 0,5 or 1 of ISO 5893.An inertialess
35、dynamometer shall be used.5.3 GripsThe grips shall be capable of holding the test piece without slippage.Self-tightening grips are recommended.For strip test pieces, provision shall be made to maintain the strip in the appropriate plane of the grips during the test, for example, by attaching suffici
36、ent weights to the free end of the test piece or by fitting a supporting plate, coated with a low-friction material, such as polytetrafluoroethylene (PTFE), to the non-driven grip.5.4 MandrelFor testing ring test pieces (type 6 and type 8), a mandrel shall be provided that is a close sliding fit in
37、the test piece. This mandrel shall be capable of being fitted into the driven head of the machine so that it will rotate freely during the test.6 Test pieces6.1 Types of test piece6.1.1 GeneralEight types of test piece are specified to cover the range of hose constructions and bore sizes normally en
